35 and trying for kid number 2 with irregular cycles

I had my first child at 33 almost 34 my period was 3 weeks late before trying with him, and we got pregnant first try. I just turned 35 and we started trying for the first time last month. My period is late as usual but I know I’m not pregnant. I’m also overweight and 25 pounds heavier than when I was pregnant with my son. I also have high blood pressure. I’m also worried that it won’t be as easy to get pregnant this time. My question is did anyone have similar issues to me and have no problem getting pregnant the second time?
